IL-33 Antibody

• Catalog Number: orb345134
• Category: Antibodies
• Description: IL-33 antibody
• Clonality: Polyclonal
• Species/Host: Rabbit
• Isotype: IgG
• Conjugation: Unconjugated
• Reactivity: Human
• Form/Appearance: Lyophilized
• Concentration: 1.0 mg/mL
• Buffer/Preservatives: None
• Purity: This purified antibody has been heated to 56°C for 30 minutes. In ELISA and other immunoreactive assays, this antibody will recognize both native and recombinant human IL-33 in cell supernatants and certain body fluids. A control of similarly diluted normal rabbit IgG is recommended.
• Immunogen: This purified antibody was prepared from whole rabbit serum produced by repeated immunizations with full length recombinant human IL-33 protein.
• UniProt ID: O95760
• Tested applications: ELISA, WB
• Dilution range: ELISA: 1:20,000 - 1:100,000, WB: 1:500 - 1:2,000
• Application notes: This purified antibody has been tested in western blotting. Reactivity is also expected in ELISA, neutralizations, radioimmunoassay and immunohistochemistry. The endotoxin content is estimated to be < 10 pg/µl by the LAL method. By western blot a band approximately 18 kDa in size corresponding to mature human IL-32α protein is expected in the appropriate cell lysate or extract. Specific conditions for reactivity should be optimized by the end user.
• Antibody Type: Primary Antibody
• Storage: Store vial at 4° C prior to restoration. For extended storage aliquot contents and freeze at -20° C or below. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4° C as an undiluted liquid. Dilute only prior to immediate use.
• Alternative names: rabbit anti-Interleukin-33 antibody, rabbit anti-I
• Note: For research use only
• NCBI: 15559209

Western blot using Biorbyt's anti-Human IL-33 antibody shows detection of a band ~18 kDa in size corresponding to recombinant human IL-33 (lane 1). The identity of the higher molecular weight band is unknown. Molecular weight markers are also shown (M). After transfer, the membrane was blocked overnight with 3% BSA in TBS followed by reaction with primary antibody at a 1:1000 dilution. Detection occurred using peroxidase conjugated anti-Rabbit IgG (p/n orb347654) secondary antibody diluted 1:40000 in blocking buffer (p/n orb348637) for 30 min at RT followed by reaction with FemtoMax™ chemiluminescent substrate.
